Abstract: A spray gun and a method for use thereof comprises a spray gun body, an air cap, a fluid spray nozzle having a fluid tip, a hollow needle, at least one air distribution channel for atomizing air, and at least one air distribution channel for fan air, wherein the fluid spray nozzle and the air cap are configured to direct an atomization airflow at an angle of 10 to 75 degrees, preferably 15 to 60 degrees, and more preferably of 30 to 45 degrees (relative to the coating composition jet) into composition jet, and the fluid spray nozzle and the air cap are configured to provide an atomizing air pressure to fan air pressure ratio (AA/FA) of 0.1 to 10, preferably 0.5 to 1.0, more preferably of 0.6 to 0.9, and still more preferably of 0.66 to 0.88.

Abstract: A paint spray gun comprises a spray gun body; an air cap; and a hollow needle capable of assuming at least an open position enabling the passage of paint therethrough and a closed position; at least one air distribution channel for atomizing air; and at least one air distribution channel for fan air. A fluid spray single two stage nozzle includes first and second internal surfaces at first and second predetermined angles, respectively, with respect to a rotational axis of symmetry of the nozzle, wherein the first angled surface is proximate a forward opening of the nozzle, the second angled surface is aft of the first angled surface, the first angle is in a range of substantially 0.05 to thirty degrees, and the second angle ranges from substantially 0.1 to sixty degrees greater than that of the first angle.

Abstract: A spray gun and a method for use thereof comprises a spray gun body; an air cap; a fluid spray nozzle having a fluid tip; at least one air distribution channel for atomizing air; and at least one air distribution channel for fan air, wherein the fluid spray. The fluid spray nozzle and the air cap are configured to direct an atomization air flow at an angle of substantially 10 to 70 degrees relative to the liquid coating composition jet, into the pre-atomized coating composition jet and produce an atomization air pressure to fan air pressure ratio of substantially 8.0 to 1.5.
